USPS Form 1583

The Postal Service form that authorises a mail receiving agency to accept post for a person or company, with identity checked by the agency or a notary.

The short answer, then the detailChecked September 2026

The detail

What it means in practice.

Every virtual mailbox needs one. You identify yourself and the company, list who may receive mail, and sign in front of the agency or a notary, with two forms of identification. Most agencies arrange this online for customers abroad. Without it, the agency can't accept the company's post.
